Ion-conductive　elastomers　capable　of　damping　can　significantly　mitigate　the　interference　caused　by　mechanical　noise　during　data　acquisition　in　wearable　and　biomedical　devices.　However,　currently　available　damping　elastomers　often　lack　robust　mechanical　properties　and　have　a　narrow　temperature　range　for　effective　damping.　Here,　precise　modulation　of　weak　to　strong　ion-dipole　interactions　plays　a　crucial　role　in　bolstering　network　stability　and　tuning　the　relaxation　behavior　of　supramolecular　ion-conductive　elastomers　(SICEs).　The　SICEs　exhibit　impressive　mechanical　properties,　including　a　modulus　of　13.2 MPa,　a　toughness　of　65.6 MJ m−3,　and　a　fracture　energy　of　74.9 kJ m−2.　Additionally,　they　demonstrate　remarkable　damping　capabilities,　with　a　damping　capacity　of　91.2%　and　a　peak　tan　δ　of　1.11.　Furthermore,　the　entropy-driven　rearrangement　of　ion-dipole　interactions　ensures　the　damping　properties　of　the　SICE　remain　stable　even　at　elevated　temperatures　(18–200 °C,　with　tan　δ　＞　0.3),　making　it　the　most　thermally　resistant　damping　elastomer　reported　to　date.　Moreover,　the　SICE　proves　effective　in　filtering　out　various　noises　during　physiological　signal　detection　and　strain　sensing,　highlighting　its　vast　potential　in　flexible　electronics.　©　2024　Wiley-VCH　GmbH.
